- Women with a positive pregnancy test at screening. Women of childbearing potential, who were pregnant or lactating, seeking pregnancy, or failing to take adequate contraceptive precautions (e.g., an oral or injectable contraceptive, an approved hormonal implant or topical patch, or an intrauterine device). Should a female subject become sexually active, she must have agreed to use a double-barrier method or barrier plus spermicide. A woman of childbearing potential was defined as any female who was less than 2 years post-menopausal or had not undergone a hysterectomy or surgical sterilization, e.g., bilateral tubal ligation or bilateral ovariectomy (oophorectomy). Females who were post-menopausal were confirmed by the follicle stimulating hormone (FSH) test at initial screening.
